Graph 3/6 3/4 and 3/12 on a number line

Plot left to right 3/12, 3/6 and 3/4 at their corresponding values.

Step-by-step explanation:

When using a number line divided into parts of 12,  convert the fractions to a denominator of 12 through multiplication.

is the same.

Plot the values on the number line.

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
